ROTARY STAMPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 283,871, dated August 28, 1883.

` Application filed January 31, 1883. (No model.)

. To all whom it may concern.-

Beit known that I, PHTLLTPJ? DEINKAUs, .I r., of Detroit, in the county of Vayne and State of Michigan, have invented new and useful Improvements in Rotary Stamping-lVIachines;

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to machines for man;

ufacturing ornamental composition strips, which are employed as ornamentation to the fronts of picture-frames, by means of which such strips can be manufactured in indefinite lengths.

rIlhe composition ornamentations applied to the fronts of frames have hitherto been made by working the composition into lengths of about twelve inches and then stamping the face side of such composition with the pattern desired. This is a slow and tedious process, and one which requires the adjacent ends of the various strips to be matched in laying the same upon the frame, and it frequently also happens that the depth of the imprint of the ornamentation-pattern so varies as to create an unpleasant appearance to the eye when the frame is finished.

It is the object of the present invention to provide a machine by means of which perfect work will be done, the imprinting or stamping of the ornamentation being uniform upon a strip, which may be continued to an indefinite number of feet in length.

The invention consists in the peculiar construction of the parts of the machine and their combination and operation, as more fully hereinafter described.

Figure 1 isa perspective view of my machine. Fig. 2 is a detached elevation of the ornamentation-roll, the view being taken from the front thereof.

In the accompanying drawings, which form a part of this specification, A represents a bed, upon which are j ournaled two drums, B, which carry an endless belt, C, upon which the composition is placed to feed the machine. An-

` other pair of drums, I), carry another endless belt, E, which carries ofi' the finished ornamental strip as it passes from the machine. F is a smooth-faced iron roll, suitably j ournaled at each end to the frame, and G are suitable standards or brackets rising from the top of said frame, and to these brackets, by means of boxes H, which are vertically adjustable by means of set-screws I, is journaledthe ornamentation-rolly J. The drums B D and roll F are upon the same plane, and may bc driven ,from any suitable source of power. The ornaproject beyond the face of the .wheel itself by just so much as the thickness of the composition or the strip, so that as the latter is fed in from the endless belt C by the rotation of the roll F aud wheel J, it is drawn between them, receiving the impress of the wheel upon its face side, while at the same time the diskcutters trim the edges parallel with each other. The shaft upon which the wheel J is secured may be so journaled as to be readily removed for the purpose of substituting any other pattern of ornamentation-wheel, and to this end one or both the disk-cutters may be so secured to the shaft as to readily be removed.

By means of a device constructed and operating substantially as above described I am enabled to turn out this particular style of work with great rapidity, very uniform and even, and at but a moiety of the expense attending its manufacture as ordinarily done.

It will be observed that as there is a space left upon each side of the roll F, and between it and the drums B D, the composition fed upon the apron @would fall intoV one of these spaces. In order to prevent this, I use upon each side of the roll F a bridge, S, (shown detached in Fig. l and in dotted lines upon the same figure,) the top of this bridge being at or about the same plane as the top of the drums B D and roll F, so that the composition strip will pass over this bridge from the carrier-belt to the roll. Upon this bridge I secure so as to IOO 2 sssu vertical guide-rolls U. The object of making 2.
